FILTER
This unit must not be operated without a filter. It comes
equipped with disposable filters, which should be
checked often and replaced if dirty. Insufficient airflow
due to undersized duct systems or dirty filters can result
in nuisance tripping of the high or low pressure control.
Refer to Table 2 for correct airflow and static pressure
requirements. (See Figures 3A & 3B.)
CONDENSATE DRAIN
Determine where the drain line will run. This drain line
contains cold water and must be insulated to avoid
droplets of water from condensing on the pipe and
dripping on finished floors or the ceiling under the unit.
A trap
MUST BE i nstalled in the drain line and the trap
filled with water prior to start up. The use of plugged
tees in place of elbows to facilitate cleaning is highly
recommended.
Drain lines must be installed according to local
plumbing codes. It is not recommended that any
condensate drain line be connected to a sewer main.
The drain line enters the unit through the 3/4" FPT
coupling on the coil side of the unit.
PIPING ACCESS TO UNIT
Water piping to and from the unit enters the unit casing
from the coil side of the unit under the return air filter
rack. Piping connections are made directly to the unit
and are 3/4" FPT for models 24 - 42, and 1" FPT for
models 48-60. (See Figure 4.)
